Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full disclosure burden. It does disclose two useful traits — 'pay-per-call' (cost implication) and 'Task text discarded' (inputs are shape-checked, not processed) — which the schema's repeated 'discarded after...' notes corroborate. But it omits side effects, network behavior, and cost magnitude, and gives no safety profile for a tool that appears to consume foreign URLs and feeds.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, each earning its place: purpose, return artifacts, and the key discard behavior, with the purpose front-loaded. It is dense and efficient with no filler words. The middle sentence's jargon list ('CLI setup, how-it-works, skill file, remote MCP hops') is cryptic, but that is a clarity problem rather than a structural one.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 9 parameters, zero annotations, and no output schema, the description is incomplete: it never explains how the parameters relate to the stated purpose, what the return artifacts look like, or when to choose this tool among 26 siblings. The schema's discard-heavy parameter descriptions actually deepen the confusion by suggesting inputs do not influence the outcome. Minor credit for enumerating the return artifacts.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3 — each of the 9 parameters is individually documented in the schema. The description adds only the unifying note that task text is discarded, which matches the schema's 'discarded after...' language but adds no per-parameter meaning. Critically, it never connects the 9-parameter grab bag (city, zone, query, json, feed...) to the stated gateway-finding purpose, so an agent cannot determine which parameter to supply.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific resource ('public pay-per-call tool gateway (Monid)') with a verb ('Find') and enumerates return artifacts ('CLI setup, how-it-works, skill file, and remote MCP hops'), so it avoids tautology. However, the core terms are unexplained jargon — an agent cannot tell what a 'Monid' gateway is or what the returned hops mean — and nothing in the description distinguishes this tool from its 26 siblings. It states what is found but not what the tool effectively does.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use guidance appears anywhere in the description; it neither names alternatives nor gives selection conditions despite having 26 siblings such as web-fetch, normalize-url, and status-catalog. 'Task text discarded' weakly implies this tool is not for task execution, but that is a behavioral note rather than usage direction. An agent has no basis to prefer or avoid this tool in any given situation.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
